JOSEPH HULTZ, OF

PATENT Frio MANSFIELD, OHIO.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 683,856, dated October 1, 1901.

Application filed April 27, 1900.

To @ZZ whom t may concern:

Be it known that I, JOSEPH HULTZ, a citizen of the United States of America, residing at 131 East Fifth street, Mansfield, Richland county, Ohio, have invented a new and useful Oar-Brake, of which the following is a specification.

Myinvention relates to improvements in a car-brake in which a sheave-pulley having a ratchet-wheel on each side thereof and made integral with said sheave-pnlley operates in conjunction with two levers, the function of one lever being to lock or brake the wheels of a car or other vehicle and the function of the other lever being to release said wheels at the will of the 'operator'. Y

The objects of my invention are, first, to provide a brake that is powerful and positive in its operation and means to operate said brake that will produce a maximum pressure or friction against the Wheels, thereby retarding them more or less with a minimum amount of physical exertion; second, to construct a brake that is simple, eflicient, practical, quick, and positive in action, and, third, to construct a brake that can be attached to any part of a car or other vehicle and operated with safety and efficiency on the end, top', or platform of a car when the brake is applied to the wheels of the car or released. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the entire brake. Fig. 2 is a detailed View in perspective of the brake-lever. Fig. 3 is a detailed view in perspective of the releasing-lever. Fig. 4 is a side view of the brake, showing the brake locked and the method of connecting the brake-chain to the brake-rod.

Similar letters refer to similar parts throughout the several views.

The bed-plate A and the standards or bearings B B constitute the framework of the brake. A shaft C is fitted and jonrnaled in the standards B B, to which is attached and keyed solidly thereon a sheave-pulley having ratchet-wheels D D on each side thereof and made integral with said sheave-pulley. A staple E, bolt, screw-eye, or any other suitable fastening device is attached 'to the saranno. 14,609. (remodel.)

sheavo-pulley in the center of the groove. To said fastening device E a chain F is attached and passes around the circumference of said sheave-pulley and roller G and is attached to the brake-rod. A lever I is fitted loosely on the shaft C, having an ear or ange J projecting upwardly f rom the upper side of the lever and extending on one side of the lever I far enough to bring it in alinement with the ratchet-wheel. In said offset or extension a slot is cut, into which the end of the pawl K is inserted and held in position by the bolt L, which passes through the ears and pawl K. Said pawl has an ear M extending from the top with a slot cuttherein. A connecting-bar N is inserted in the slot and is connected with vthe wing of the small lever O by means of the bolts P P.

The lever O is attached to the lever I by means of a bolt Q at a point on the lever I which will bring the handles of the lever I and O in alinement with each other. A coilspring is attached immediately under the lever I on one end and to the bolt P, which passes through the wing of the small lever O, the purpose of which is to keep the pawl K in contact with the ratchet-wheel.

To the bed-plate A a brace V is attached to hold the lever I in position. position of said brace has a rest made integral with said brace and when attached to the bed-plate sustains the lever in an upright position when not in use. On the opposite side of the sheave-pulley and immediately under the ratchet-Wheel a releasing-lever T is attached and connected with a pawl of peculiar construction, forming a toggle-joint.

To the bed-plateA two standards R R are att-ached. A pawl S is inserted in the slot of one of said standards and held in position by a bolt. The pawl S is formed and shaped so that it will come in contact with the teeth of the ratchet-Wheel atthe center of its diameter, thereby securely locking the brake. The other end of the pawl S is made heavy, the purpose of which is to hold the pawl in contact with the ratchet-wheel by gravity. To

the end of said pawl S the releasing-lever T, having a slot out in the end thereof for the purpose of connecting said lever to the pawl The upper IOO S, is attached. The releasing-lever is attached and held in position by means of the Standard It, close to the end ol the lever T.

In the lever T a slot is cut to permit the pin U to pass. A coil-spring XV is placed on said pin and presses on the under side of the lever T, holding the pawl S in contact with the teeth ot' the ratchet-Wheel and locking the brake.

It is obvious that my brake can be used on all kinds of' vehicle-Wheels Without deviating from the principle and is especially adapted for street-car service.

IIaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A car-brake composed of a sheave-,pulley having ratchet-wheels on each side thereof, a brake-lever fitted to rotate loosely on a shaft having an ear or flange projecting from the upper side thereof, With a slot out therein to receive a pawl adapted fo come in contact with the teeth of the ratchet-Wheel, a pawl journaled in said slot having an ear or flange formed thereon with a slot cut in said ear or flange to receive a connecting-rod, a connecting-rod to the ear or flange of said pawl adapted to be connected to a lever, a coil-spring attached to the lever I and the Wing of the lever O adapted to keep the pawl in .contact with the ratchet-wheel.

2. The combination in a car-brake, of a sheave-pnlley, ratchet-wheels made integral with said pulley, a brake-lever fitted to rotate loosely on a shaft, having an ear or flange projecting upwardly from the upper side thereof, with a slot. cnt therein to receive a pawl, a pawl jonrnaled in said slot having an ear or ange formed thereon with a slot cut in said ear or flange to receive a connecting-rod, a connecting-rod attached to the ear or flange of said pawl, a small lever, having a wing Athereon to connect with said rod, a coil-spring, attached to the lever I and the Wing of the lever O, and adapted to keep the patvl K in contact with the teeth of the ratchet- Wheel.

3. A car-brake composed of a sheave-pulley, ratchet-Wheels made integral and keyed solidly on a shaft, said shaft jonrnaled in fixed bearings, a brake-lever loosely journaled in a shaft, `having a lever and pawl attached thereto and adapted to be brought in and out of contact with the teeth of the ratchet-Wheel, a releasing-lever attached to a standard with a pavvl connected to the end thereof adapted to come in contact with the ratchet-Wheels,said releasing-lever independent of' said brake-lever and adapted to normallyand automatically engage said ratchet- Wheel..

4. The combination in a car-brake of a locking-pawlhaving one end fitted to come in contact With the teeth of a ratchet-Wheel, and attached to the bed-plate A, a releasing-lever,

eut in the releasing-lever, a coil-spring fitted thereon, and pressing against the under side of the releasing-lever, thereby locking the pawl in positive contact with its respective ratchet-wheel.

5. A car-brake composed of a sheave-pulley having ratchet-Wheels made integral, a brake-lever loosely journaled on a shaft, a jointed releasing-lever attached to a bedplate and adapted to release said brake, the brake automatically and normally engaging the ratchet-Wheel, a rest attached to the bedplate A adapted to hold and retain the brakelever in position substantially as and for the purpose set forth.
